The Alternative to Down

Guide

Insulation

A synthetic-insulated jacket with relatively little insulation makes an excellent choice as a versatile mid-layer when you're moving or your primary layer when you're just hanging out by the campfire. Opt for a jacket with more insulation if you're standing around while belaying an ice climb or you know you'll encounter brutally cold weather.

Waterproof Rating

Most synthetic-insulated jackets use a lightweight or medium-weight nylon shell with a water-resistant DWR coating. However, a puffy with fully waterproof fabric will be worth its weight in gold if you think you'll encounter wet weather. Related ContentWaterproof Technologies & Materials

Fit

How you use your jacket determines which fit is best for you. Choose a slim, athletic, or medium fit if you'll wear your down jacket as an insulating mid-layer, or opt for a loose fit if you plan to layer your down jacket over everything else.
